Application'J uly 23, 1942, S erialt No. 452,012 I 4 Claims. (01.230-1117) 1 *invention relates to a blower housing and the combinationofjthe housing and a'motor having wideaDPliCatiOnaIthough intendedprimarily for blowing 'coolingair over the tubes of a radio receiver ortransmitter. Thebloweris driven by a smallmotor of which there are agreat many style and different dimensions, the housing is constructed sothat it is easily adapted to receive any style of motorgwith theirwidely differing bases or attaching means. I I v 'It' isfan objectiofthe invention -toconstruct a blower housing'which is adapted to mountany style of. small motor which drives'the impeller within the blowerhousing.

Another object of the invention is to construct a blower housing whichis adapted to bemoii'nted in a. great. many different positions therebypermitting the greatest degree of latitude inth'positibnin which thehousing. may be; mounted when Putin use I "'A still further object "ist6 eons tructamowr housingand motor assembly which affords a widevariety of ways in which a motor and the housing may be. securedtogether and may be secured to some supporting structure.

Other objects of the invention will'be more apparent from the followingdescription taken in connection with the accompanying drawingillustrating a preferred embodiment thereof, in

which: c

Figure 1' is a side elevation of the blower housing. I

Figure 2 is an elevation of the housing with a bracket for securing thesame to a supporting structure.

Figure 3' is a View of a flatplate forming one side of the housing towhich a motor has been secured. The motor is shown attached to anysuitable structure such as the wall of a radio chassis. v

- Figure 4 shows a blower housing with a motor secured thereto inanothermanner and the assembly mounted upon a. wall or other supportingstructure.

Many radio sets require a cooling stream of air to be. blown into thecabinet so that it will circulate over the tubes and to dispel theheated air from within the chassis or case. Such a blower must becapable of being mounted within the chassis in a great variety of ways.Again, a parblowerhousing must be capable of receiving any styleoffm'ctor. 1 f v l e blower housing has a body portion which preferablyis of plastic or'molded .materiaLi A molded. housing is split throughthe center thereof .to'fo'rm body sections I0 and II. The body portionor particularly body section III has a side wall in {whichthere -.i anair inlet opening not shown. The twosections of. the body when.assembled have an outlet opening I2 which directs a stream of air fromthe blowerv housingin the direction desired. i

The body or particularly the body section I I- has an .open side throughwhichthe blowerimpeller is insertedwithin the housing. 3 The open sideiscovered by a plateIE whichis preferably flat, so that it may be easily.drilled to receive" screws ,IB which secure the motor IT to the plate.and-house ing. ,Screw'holesmay be drilled anywhere in the plate therebyadapting the blower housing to be driven by a motor haying any style ofbase or se-v curing means. I'Il'iefplate has a hole I8 through which themotor shaft I9 projects .and the blower impeller is secured to the motorshaft.

The flat plate is secured to the housing by screws 2|. These screws alsosecure the two halves of the housing together by having threaded nutsembedded or molded into the body section I0 and screw holes are thenprovided in the body section II in alignment with the nuts. The screws2I therefore secure the flat plate and the body sections II and I2together to form the complete housing. The screws 2| .have a variedspacing with respect to each other and also with respect to the motorshaft opening I8 thereby rendering the screws available for a widevariety of mountings for the housing and motor.

In Figures 1 and 2 a bracket 22 may be secured to the housing byone ormore of the screws 2| and the bracket in turn is anchored to some partof a, radio chassis or other piece of mechanism upon which the bloweris'to be mounted. The motor H, in beingsecured to the plate I5, and

the blower are therefore mounted as a unit in position by the bracket22.

Figures 3 and 4 each illustrate another way in which the motor andblower may be mounted and suggest the many other ways in which thecombination of motor and blower may be secured together and the assemblymay be secured to any supporting structure. In Figure 3 the motor issecured to the plate I5 and the plate I5 carries the body portion of theblower housing. The motor, however,'carries a bracket 24 which issecured to the motor by screws 25 which utilize the securing means orscrew holes already provided with this style of motor. The bracket 24 isin turn secured to a wall W by a screw 26 to mount the motor and blowerin a desired position.

In Figure 4, still another style of mounting is illustrated for a motor28 having a different style of base or securing means. This style ofmotor ha s curing means in the periphery thereof, and cons quentlyrequires a bracket 29 which is secure to the motor by screws 30. One endof the bracket may besecured to the blower housing by one of the screws2| and the other end of the 2. A blower housing comprising a bodyportion formed of sections and with a completely open bracket may besecured to a supporting structure such as a chassis wall W by screw 3|.

The three embodiments of mountings illustrated are merely indicative ofthe wide adaptability of the blower housing to receiveany style of motorand having any style'of base or securing means. The drawings alsoillustrate a wide variety of ways in which the motor and blower assemblycan be mounted in any desired position wherever used such as in a radiochassis.

This invention provide an improvement inv a blower housing and assembly.It is understood that various modifications in structure, as well aschanges in mode of operation, assembly, and manner of use, may andoften'do occur to those skilled in the art,.especially after benefitingfrom the teaching of an invention. This'disclosure illustrates thepreferredmeans of embodying the invention in useful form.
